TO ALL WHOM IT MAY, conennm v v Be it known that I, AUGUSTUS B. W001 ofHamburg, Ashley county, and Stateot' Arkansas, have invented a certain new, useful, and improved Machinotfor Increasing Mechanical Power without loss or diminution of speed; and I do herehydeclar'e the following to b'e-a full, clear, and exact description of the same, reference. being hnd to the nnnexed drawing, making a part of this specification, which exhibits a perspective viewof my invention in its simplest form. V

' The object of my invention is to increase the power of any given motor engine or machine, without making any inherent positive addition thereto, by thegnso of mechanical agencies that are entirely extraneous and. n distinct from said-motor, excepting so far as they are connected therewith in the operation of the same; and to. do this I interpos'e 'between the point at which the power of said machineis'direetlyapplied, as, for example,

. its crank and the point at which the increase of power is to be attained-and applied, an intermediate system of gearing consisting of certain cogged or ratchet-bars, and cogged or ratchet oscillating segments, operating cranks progressively increasing in length at the same rate" of motionas the first or driving-crank, :ind with the 7 same proportionate'power. But my invention will bebe tterunderstood by reference to the drawings Adi/ 21'? the driving-wheels through which power andmotion are communicated from the engine operating them, (the engine is not shown on the drawings,) by'means of the pitmen a a" connected to crank-pins. or wrists 'b b. 'Ex tending jnst half way around the circumferenceor perimeters of these driving-wheels A A are cogged segments a c, which fit into ratchet or cog-bars BB that are sustained by and slide upon suitable slide-bars 1 and 2." The driving-wheels A A, not revolving. the-segments c e, have. avibrating or oscillating motion of not quite but very nearly ninetydegreoasWQep; that-is to'say, the stroke of the cylinders which" operate the segments 0 c' is just short of what would'be required to revolve the driving-wheels, and hence the crank-pins b b vibrate backwards andforwards in the arc of a circle above the axes of the said driving-'- wheels, and oil cours'ecarry the segments with them. The wrist or crank-pins b b are so placed with reference to their ares, that the lengtho t' the cogged bars B will be onthird greater than the diameter of the drivingwheels A A, in order that theforlner may correspond in length with the length of the segments 0 c. Intermediate wheels C C, havinga'diameter exactly equal to the length of the bars 13, B, are connected to the latter b y menns of links orarms d d and-wrist or crinlbpinsc 2. These intermediate wheels C C are also provided, like the driving-wheels A, n'ith'cog'segments extending half way around theiriperimeter, which work in and are operated. by'ratchet sliding-bars D D',-the length of which is one-third greater than the .diameter of the I said intermediateyheels, G To the-sliding-bars' D1) are connected the crank-wheels E E by means-"oi" linksff' and crank-pins g g The crank-pins g g are-twice as far from the ones of wheels E E as the cranlp pins 6 b. are from the axes of wheels A A, or, in other words, the cranks upon the former are twice as large as I the cranks upon the latter, and hence it follows that the'power gained is equal to rather more, in practice thsn two-for one, less of eourse the loss or diminution from friction. When the partners nicely adjustednnd work smoothly this loss is comparatively insignificant, so that one may assume. the actual gain of power is ab'out a s above stated, two for one. In placing the crank-pins "9" in the wheels E E, care must be taken so to fik them that their respective dead-points are forty-five degrees apart. This secures a corresponding relative adjustment of allthe cranks, and henccn regular and constant application of power. Between the crank-wheelsE E is a belt-pulley or drum, F, through the medium of which the increased power that has been gained is afpplied to use. I prefer ahelt-pulleyi but obviously a'cog-wheel-nxay be substituted in lieu, thereof, for the purpose of applying the increased-power if deemed desirable. v

I have not considered it requisite to'describe herein, nor to exhibit upon the drawings, more than one intermediate system of gearing; but any number may be used. The greater the number that areinterpossd between. the p'oiutof direct application and the .desired point of' application, the greater the increase ofpower,

Having thus described my invention, what-I claim, and desire tosecnre-hy Letters-Patent, is--- The interposition of intermediate mechanicslfparts or gearing between. the point of direct application of power, and the point at which an increase of power is attained and applied for the purposej of increasing the aeity or power of any givenmotor engine or machine when the same-is efl'ected substantially in the manner P 7 and by the means herein described. p I
